[PATCH 2/3] kfence: allow create debugfs dir/file unconditionally
Posted by yuan linyu 1 month, 3 weeks ago
When add boot parameter kfence.sample_interval=0, it will not create
debugfs dir/file, but when user change this parameter after boot,
it can enable kfence, there is no debugfs info to check the kfence
state.

Remove kfence_enabled check in kfence_debugfs_init() to create debugfs
unconditionally.
